Another unusual sub for the small collection of WW1 subs.
17 of these were built. The idea was to have a sub that could operate with the battle fleet. This meant that speed was important. They were powered by oil fired boilers driving two Parsons geared turbines, this gave a speed of 24 knots surfaced. Submerged speed was eight knots driven by electric motors which were charged by a diesel generator. Conditions below must have been horrendous.
At 340ft long and 1980 tons surfaced, these were big ships by sub standards, submerged the displacement rose to 2566 tons.
Safe diving depth was 200 ft, far less than the overall length.
Submerging could take up to 30 mins. Boilers had to be shut down, funnels lowered and the ship sealed against the ingress of the sea and the electric motors coaxed into life.
The design wasn't considered to be a success, they became known as the "Katastrophy class".
The original design was modified by the introduction of the bulbous bow (see pics) to improve the sea-keeping qualities but this didn't make a great deal of difference.
They were crewed by 59 officers and men.

Will enjoy this one - will it be at the "Battle of May Island" ??????
-
Dunno yet, at the moment it's at the battle of Brookland road.

And so to the build.
The parts count is quite low, numbered up to 25, there is a small etched fret. As the model is water-lined, some of the parts aren't used.
Assembly of the plastic including water-lining probably took no more than a couple of days, then the fun starts.
First problem is that the top section of the conning tower is non existent, not included in the kit and not shown on the instructions so a scratch built one was produced out of some scrap PE 0.004" thick.
Although it doesn't really matter, the instructions are a mirror image of the model!
There are no railings included in the kit. Looking at lot of pictures, there definitely were railings fitted but may have been taken down at sea. The other thing is that the stanchions were a long way apart.
By fair means and foul, I've come up with a figure of 15mm between stanchions.
Some scratch-building will be in order, so we need a plan.

Looks like the plan has worked up to now.
Haddock.
There's a shot of some railings to show the distance apart of the stanchions, poor pic but best I can find.

Looking good Tony. Between you and Kevin there's going to be a whole fleet of subs.

It could be a SUB - division of the club.

Never knew this Sub existed. Real interesting stuff.
Thanks Haddock.

SUB standard joke. ::)

Quick change the SUBject!

With the amount of subs you 2 have - it will need a SUBstantial table to hold them all

Always excellent, never Substandard

SUBsequently we'll move on. I know you said it was long but it looks so long in the photos, bet it was unstable.

Hi All,
From the 'SUBS' bench, it really looks an interesting beast.
I still cannot get my head around the fact that this was in main steam powered and need to be sealed before submerging.
Those guys who designed this were either geniuses or obsessed.
Cheers,

They can't ever have been to sea!!

Like a lot of things - it sounded good on paper - and the designer NEVER HAD TO USE THE PRODUCT >:( >:( >:( >:( >:( >:(
-
Stanchions added, primer sloshed on.
-
Looks good and he stanchions are excellent.
did it only take a week from box to built?
I'm doing something wrong

A Yorkshireman would have said... If its that B....Y good, you take the dam thing for a swim!
Looking good Mr Haddock.

Probably less, I'm doing bits at in between other stuff.
-
Paint added. Bit and bobs and railings needed to finish.

Are they twin funnels?

Yup, they had to be taken down and sealed from the sea before diving!
Haddock.

That must have taken some time.
Sounds more like a Steam Punk machine.

Reportedly 30 mins to dive!
-
30 mins to dive BUT the engine room was still very very very hot - even thou the engine was shut down it still gave off lots of heat as it was cooling down - who would want to be an engineer on that ship.

All these Subs are getting to me! I think they all look great!
I could get interested in doing some if I was 20 years younger!
-
Looks great.

Guess that's it folks, ugly looking thing innit!

Lovely, but some sea needed.

I presume the masts were also taken down when it dived?
-
Think so, it looks as though they could have telescoped into the hull.

Another masterpiece.
-
Great stuff!
-
Cracking subject, Cracking model.
Superb.
-
Beautiful work Haddock, as always.

Maybe you submarine Guys should get together and mount one submerged! There's a thought!
Maybe nosing through a tethered minefield? ..

By tethered Minefield, do you mean negotiating, all those modellers at a model show, intent on on a bargain, but less on a shower or personal hygiene??
